FAST. PRECISE. UNIQUE.

CHERRY REALKEY-TECHNOLOGY

CHERRY RealKey analog technology - or in short CHERRY RK - is a completely new approach for reading
key signals. Instead of digitally scanning the switching points, each key is simply connected
to the analog controller. This results in as yet unprecedented advantages
over any existing technology:

INDIRECT. INACCURATE. OUTDATED.

DIGITAL TECHNOLOGY HAS ITS LIMITATIONS

The performance of digital controller technology has systemic limitations. In terms of speed and precision
in signal processing, this technology is not able to provide an optimum performance.
The weaknesses of digital technology:

Delay
Unnecessary time is wasted between pressing the button
and processing the signal.

Key rollover
Only a certain number of keys
can be read out simultaneously.

ANALOG TRANSFER

FASTEST RESPONSE TIME

Fastest response time

With CHERRY RealKey technology
there are different voltages at the individual
conductor tracks. When the circuit is closed
by the press of a button, the controller detects how much current is flowing. So each key
on the keyboard is read analogously
in realtime by the controller.

The result

This means that the response time between pressing the key and signal processing takes only 1 millisecond instead of the previous average of 20 milliseconds.

UNLIMITED SIGNAL PROCESSING

PROCESSING ROUTINES

LIMITED SPEED

Limited speed

Most keyboards still use digital technology. Here, a controller with continuous pulses scans the individual contacts of the switch matrix to detect whether a key has been pressed and thus a circuit has been closed.

The result

When a key is pressed, the controller unit must first calculate and process various routines. An ordinary keyboard with digital technology needs approximately
20 milliseconds to do this.

LIMITED SIGNAL PROCESSING

FULL-N-KEY ROLLOVER

UNLIMITED SIGNAL PROCESSING

Highest precision

The analog connection between
the controller and each keyswitch
guarantees the highest precision.

100% anti-ghosting

CHERRY RealKey technology enables afull-N-key rollover and 100% anti-ghosting. Therefore all the the keys can be pressed simultaneously, without causing any errors.

GHOSTING

LIMITED SIGNAL PROCESSING

Key rollover

Due to the functionality of digital
technology, only a limited number of
signals can be processed by keys
that are pressed at the same time.
This effect is referred to as key rollover.

Ghosting

In addition, what is known as the ghosting effect may occur, which means the controller incorrectly identifies and transmits a signal that does not exist.
